ALARM-CLOCK.

Application filed October 28, 1919.

T 0 all whom it may concern.

Be it known that I, WILLIAM PFEIFER, J r., a citizen of the United States, residing at Jersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Alarm-Clocks, of which the following is a full, clear, and concise description.

' The present invention relates generally to improvements in alarm 'clock construcdirected to the provision of means for arresting the actuation of the alarm mechanism.

In present types of alarm clocks the means employed for silencingjthe alarm is usually in the form of a small lever, finger piece or button or the like which is frequently difficult to manipulate and whichby reason of its size and disposition on the clock case frequently makes it difficult to locate the'same in the darkness or semi-darkness without the employment of some means of This is especially objectionable where the continued sounding of the alarm will serve to disturb others thanthe the signal is intended. during the period in'which the latter is endeavoring to locate the silencing medium in the dim light, or jwhile he is in the act of providing the necessary illumination to the desired end.

h The object of the present invention is to provide a means for, arresting the actuation J of the alarm mechanism of an alarm clock which may be functioned in a simple and expeditious manner so' that the sleeper upon being awakened may atonce silence the alarm, whether or not he is in a position to'observe the clock. i

A further object ofmy invention is to provide a simple and econom cal meansof silencing the alarm of a so-called alarm be cheaply manufactured of the clock and which .will not detract from the appearance thereof, or interfere with the functioning of the clock mechanism, or the alarm mechanism controlled thereby.

further comprehends a aforesaid purpose andpossessing the stated characteristics which will be of a size relative to the clock to permit of the ready manipulation thereof to positively engage and arrest the movement of the alarm mechanism, or the means Iy invention V Specification of Letters Patent ticularity the respectively, 7 indicates be well known in the art and as it forms no Patented June 14, 1921. Serial N0. 334,100.

whereby the alarm mechanism is controlled, said means being capable of cooperating with alarm mechanisms of various types with equal efliciency.

Further objects and advantages of my in vention will become obvious as the "descript1on proceeds, and in order to. afford .a clear and comprehensive understanding thereof, I have elected to illustrate and describe it in connection with certain preferred embodiments, although I would have it understood that I- do not limit my invention to the specific forms shown herein, reserving unto myself the full range in equivalents, both in structures and uses, to which I may be entitled under my invention in its broadestaspect.

Y I shall now tion with ref drawings and proceed to describe my invenerence to the accompanying then point outwith more paressential elements of novelty 111 theappended claims. 1 i

, Fig. 5 illustrates afragment of the side elevation of a clock showinga furthermodification of my invention Referring now to the drawings in detail in which like characters of reference'are employed to designate similar parts through out the several views, and more especially to the construction shown in Figs. 1 and 2, the clock casing supported vby the usual legs or standards 8. As will be observed the clock shown in Figs. 1 and 2 is of the so-called inside alarm type,

the sounding device or bell being indicated at 9, theactuation of the alarmmechanism being controlled by the lever 10 which may e moved to alarm and silent positions the finger piece 11. This structure is part of the present invention will not be described. in detail. Mounted upon the inner face of the casing 7 of the clock, preferably at points below the major diameter thereof,

I provide arms 12 and 13. These arms may be riveted, soldered or otherwise rigidly fastened to the clock casing so to provide firm mountings for the member 14, by means of which the functioning of the alarm mechanism is governed. This member 14 is preferably annular in configuration and formed from a strip of flat metal, conforming tothe configuration of the rear end of the clock casing, and is pivotally connected to the side arms 12 and 13, as shown at 12 and 13 By this means, it will be obvious that the member 14 will be capable of a rocking movement toward and away from the face of the clock on its fulcrum points provided by the aforesaid pivots 12 and 13 In order to render the alarm mechanism operable at the set time, the finger piece 11 is usually moved to the right, looking at Fig. 2, the movement of the said finger piece in reverse direction serving to silence the alarm. Therefore, in order to move the lever 10 in the proper direction for rendering the alarm mechanism inoperative, through the medium of the member 14, I have found it expedient to provide the right hand extremity of the lever 10 with a downwardly dependent flange 10, which is adapted to be engaged by the ends of the levers 15 and 16 which are pivoted together as shown at 17. The lever 15, as will be noted, is pivotally mounted within the clock casing at 18, while the lever 16 is pivotally connected with the annular member 14, as shown at 19.

From the construction thus far described, it will be manifest that when the finger piece 11 is moved to its extreme right position, the dependent flange 10 of the lever 10 wi1l abut against the ends of the levers 15 and 16 and move them on their pivots whereby the annular member 14'assumes the position shown in Fig. 1. When it is desired to silence the alarm, all that is necessary is to grasp the annular member 14 at any part above its fulcrum points, and move it toward the back or rear of the clock casing. This movement, as will be obvious, will cause the pivoted ends of the levers 15 and 16 to contact with the dependent flange 10 and move the lever 10 toward the left, or to silencing position. In the construc tion shown in Fig. 3 wherein I have illustrated my invention applied to a clock having an exposed bell 7, the annular member 14 in lieu of the. cooperating levers 15 and 16, is provided-with an arm 20 riveted or otherwise secured thereto at 21 the inner end of which is adapted to ride through a guide 23 located upon and secured to the outer surface of the clock casing by any suitable means. The inner end of the arm 20 is bifurcated or formed with a V'-shaped cut-out '24 whereby the oscillationof the clapper arm 25 may be arrested by the movement of the annular member 14 inwardly or toward the rear of the clock casin In the modification shown in Fig. 4, in lieu of the annular member 14, I employ a semi-annular member 26 which is pivotally mounted at 27 on the supporting arms 28, the functioning of the member of this form being similar to that of the member 14 with the exception that the gripping or useful surface thereof, is somewhat decreased or lessened.

In Fig: 5, in lieu of making the annular member 14 of flat strip metal, I have shown it made of wire or the like as indicated by reference numeral 29, suitable cars 30 and 31 being provided for pivotallyconnecting the said member with its supports and the operating levers.

From my disclosure, it will be evident that the provision of the annular member 14 or an equivalent structure will afford a readily accessible means for rendering the alarm mechanism inoperative so that the sounding of the alarm may be stopped by simply grasping the clock and the member 14 at substantially any part of the peripheries thereof and moving or pressing the said member toward the rear of the clock casing.

\Vhile I have shown and described my invention with reference to the accompanying dra'svings, it is obvious that various changes in details of structure may be made without departing from the'spirit and scope thereof.

I claim- 1. The combination with a clock having an alarm and mechanism actuable to function said alarm, of means for arresting the operation of said mechanism, said means embodying a device located exteriorly of the clock casing andconnected thereto, so as to be capable of movement toward and away from the clock casing, and means carried by said device adapted for engagement with an element of the alarm mechanism to render the same inactive when said device is moved in one of said directions.

2. The combination with a clock having an alarm, actuating mechanism therefor, and means for controlling said actuating mechanism of a device for operating said controlling means to silence the alarm, said device iucludlng an annular member mounted exteriorly of the clock and a lever carried thereby, adapted to engage said controlling means, said annular member being capable of movement relatively to the clock.

3.
